Yield on cost (YoC) is a development return metric equal to a project's stabilized net operating income divided by its total project cost, expressed as a percentage. Also called development yield, it measures the unlevered return a developer earns on every dollar spent to build and lease a property to stabilization.
How Is Yield on Cost Calculated?
Yield on cost is calculated by dividing stabilized net operating income by total project cost. The formula is Yield on Cost = Stabilized NOI / Total Project Cost. Stabilized NOI is the annual income the property is projected to generate once construction is complete and occupancy has normalized. Total project cost includes land, hard costs, soft costs, and carrying costs.
Because both inputs are forward-looking, yield on cost is a pro forma metric. The NOI is not yet earned and the cost is not yet fully spent, which makes YoC an estimate that carries more uncertainty than a cap rate on an existing building. Per Wall Street Prep, the yield on cost is sometimes called the "going-in" yield because it reflects the cost basis a developer enters at, before the market assigns a stabilized value.
Component | Definition |
Stabilized NOI | Projected annual net operating income once occupancy and rents normalize |
Total project cost | Land, hard costs, soft costs, and carrying costs to reach stabilization |
Yield on cost | Stabilized NOI divided by total project cost, as a percentage |
Total project cost is where discipline matters most. Omitting carrying costs, tenant improvement allowances, leasing commissions, or a contingency reserve inflates the yield and flatters the deal. A yield on cost is only as honest as the cost stack beneath it.
Why Yield on Cost Matters
Yield on cost matters because it is the primary test of whether building is worth more than buying. A developer takes on construction risk, lease-up risk, and time, so the yield on cost must clear the market cap rate for a comparable finished asset by enough to compensate for that risk. That gap is the development spread.
The margin is not optional. Per Wall Street Prep, most developers target a development spread of roughly 1.5% to 2.5% between yield on cost and the market cap rate, which means a project competing against a 6.0% market cap rate generally needs a yield on cost near 7.5% to 8.5% to justify the build. If the spread is thin, a rational developer buys an existing stabilized asset instead and skips the construction risk entirely.
Yield on cost also frames the exit. When a project stabilizes at a yield on cost above the market cap rate, the finished value exceeds the cost to build, and that difference is the developer's created value. A project built to an 8% yield on cost and valued at a 6% market cap rate is worth about a third more than it cost, before leverage.
Example
A developer plans a project with $40 million in total project cost. At stabilization, effective gross income is projected at $5 million against $2.6 million of operating expenses, so stabilized NOI is $2.4 million. Dividing stabilized NOI by total project cost gives the yield on cost. The table follows the calculation, based on the Wall Street Prep worked example.
Line item | Amount |
Effective gross income | $5,000,000 |
Less operating expenses | ($2,600,000) |
Stabilized NOI | $2,400,000 |
Total project cost | $40,000,000 |
Yield on cost | 6.0% |
The yield on cost is $2,400,000 divided by $40,000,000, or 6.0%. Whether that is attractive depends entirely on the market cap rate for the finished asset. If comparable stabilized properties trade at a 4.5% cap rate, the project carries a 1.5% development spread and stabilized value is roughly $53.3 million, about $13.3 million above cost. If the market cap rate is instead 6.0%, the spread is zero, the finished value equals the cost, and there is no reward for the construction risk.
Variations and Edge Cases
Yield on cost is not one universal figure: it shifts with how cost is defined, whether the yield is trended or untrended, and the property type's required spread. Two developers can quote different yields on the same project simply by including or excluding contingency and carry. The table separates the common variants.
Variant | Treatment |
Untrended yield on cost | Uses today's rents; more conservative |
Trended yield on cost | Uses rents grown to the delivery date; higher and more optimistic |
Return on cost | Often used interchangeably with yield on cost |
Stabilized yield | Yield on cost measured at full stabilized occupancy |
Property-type spread | Multifamily often accepts a narrower spread than office or hotel |
The common mistake is comparing a trended yield on cost against a current market cap rate. That mismatch borrows future rent growth to widen the apparent spread while pricing the exit at today's cap rate. A defensible comparison holds both sides to the same timing assumption.
Yield on Cost vs Cap Rate
Yield on cost is often confused with cap rate, and the difference is the denominator. Yield on cost divides stabilized NOI by total project cost, what it costs to build. Cap rate divides NOI by fair market value, what the finished asset is worth. Yield on cost is the developer's cost basis; cap rate is the market's price.
That distinction is the whole point of development. When yield on cost exceeds the market cap rate, the developer has built the asset for less than its finished value, and the spread between the two is created value. Per Wall Street Prep, yield on cost can be read as a forward-looking, going-in cap rate, while the market cap rate is the going-out figure the completed property trades at.
Frequently Asked Questions
What is a good yield on cost in real estate?A good yield on cost is one that clears the market cap rate for a comparable finished asset by a sufficient margin. Most developers target a development spread of roughly 1.5% to 2.5% over the market cap rate, per Wall Street Prep, so a project facing a 6.0% market cap rate generally needs a yield on cost near 7.5% to 8.5%.
What is the difference between yield on cost and cap rate?Yield on cost divides stabilized NOI by total project cost, the amount spent to build. Cap rate divides NOI by the property's market value, the amount the finished asset is worth. Yield on cost is the cost-basis yield a developer builds to; cap rate is the market's exit pricing.
What is included in total project cost for yield on cost?Total project cost includes land acquisition, hard construction costs, soft costs such as design and permitting fees, and carrying costs during construction and lease-up. Omitting contingency, tenant improvement allowances, or leasing commissions inflates the yield on cost and overstates the project's return.
